About me

Hello, my name is Sibylle. I would like to motivate you to learn biology and chemistry and, of course, also to inspire you. As a teacher with several years of professional experience, I know that students are increasingly being held to higher standards. Therefore, I am happy to supervise you over a longer period of time and discuss the learning content with you in a fun and engaging way, using everyday examples. The area of learning in genetics is particularly interesting to me, as I completed my PhD in genetics. I would be happy to support you in this exciting area of biology as well. If you do not speak German as your mother tongue, I could help you with methods that I have learned through my work as a teacher at a German international school. Book a lesson with me. I look forward to meeting you. Best regards, Sibylle

Hola mi nombre es Jose Angel, he sido profesor en la Universidad mas grande de Venezuela por casi 40 años. He pasado a retiro y me he residenciado en España, por lo que quiero transmitir mi experiencia mediante clases particulares, basadas sea en comprensión teórica o resolución de problemas, con seguimiento personalizado. Las clases se dictan en la plataforma Classgap, utilizan interacción constante con los participantes, mediante preguntas, presentación de la resolución del participante para identificar y corregir errores o sitios donde el problema no se esta analizando correctamente y por que. Solo algunas materias: Introducción a la IQ, Mecánica de Fluidos, Transferencia de Calor, Transferencia de Masa, Operaciones de Separación, Tecnología de Partículas. Especializado en Uso de Excel para resolución de problemas.
